bona e, sodium silicatefand co )ner chlorn or co er "sul iate. My improved glue may be prepared for use by either one of two methods, namely, all the ingredients may be mixed together and shipped or held in bulk, until needed for use, when the said mixture is stirred into v a ter for a. suificient time to permit the Waltert3 thorou hl im re 'nate t e mass' or t e several in gre diens may be separate mixed with the water to form the glue. In the first above method a gdered form of so- 2 silicate may be u instead of they E;

m orm t ere'of.

Tn either of the above cases the amount of water in which the mixing is performed may va somewhat with the desired thickness of t e glue needed, but it will be found that if the water weighs about two-and-ahalf times the weight of the several ingredients, a glue of good average fluidity will result.

The proportions of the several ingredients are eanut meal, one hundred parts; sixteen part s oiii ydrated lime; ten parts of sod iu ni ca rbgga te; thirty parts of sodium s1 icare; and two parts of cppmi p'l for e dr -do'fiper sulphate. The total quantity of laiif u's'ed i's complete the glue would be about four hundred parts. 4

The preparation thus produced needs no warmin or cooking to make it ready for use and 1t can be applied to the wood at any time within twenty four hours after the mixture has been prepared.

The peanut, or other kind of meal, used 5 in this glue is the ordinary commercial prod- Application filed August 11, 1926. Serial No. 128,626.

The sodium silicate is both a solvent for the meal and is also a filler. The copper chloride or the copper sulphate, whichever is used, both act as a water-proof- 111 a ent.

Flavmg, therefore, described my invention, what I claim is 2- A fluid adhesive compound adapted to form a water-resistant, strong, non-abrasive glue comprising a mixture with one hundred parts of peanut meal, of about sixteen parts of hydrated lime, ten parts of sodium carbonate, thirty parts of sodium silicate, and two parts of copper sulphate, mixed with about four hundred parts of water.
